  • the known pivotable exhaust gas flaps are actuated by means of a positioning motor arranged outside the valve device, preferably a so-called vacuum box. In this case, the negative pressure taken from the intake tract of the internal combustion engine acts against a diaphragm to which a control rod is fastened, and thus executes, against the action of a restoring spring, an adjusting movement which is transmitted to the valve shaft.
  • EP 1 030 050 A1 has disclosed an exhaust gas recirculation system with an exhaust gas cooler cooled by a liquid coolant, to which a bypass line bypassing the exhaust gas cooler is assigned. Upstream of the exhaust gas cooler, a valve device is arranged, which acts as a switch for the exhaust gas flow and directs this either through the exhaust gas cooler or the bypass channel.
  • the valve device has a valve closing member, which is designed either as a poppet valve or as a pivoting flap, wherein the drive of the valve closing member takes place in each case by a pneumatic actuator, which has a return spring in its lifting cylinder. When ventilation of the actuator (elimination of the negative pressure) causes the return spring in the actuator a provision of the valve or the flap in a preferred starting position.
  • an exhaust gas heat exchanger in particular an exhaust gas cooler was known in which - similar to the aforementioned DE 199 62 863 A1 - a bypass channel is integrated into the housing of the exhaust gas cooler.
  • a valve device is provided with a valve closing member, which acts as a switch for the exhaust stream and is driven by an outside of the housing arranged Stellmo- gate, in particular a so-called vacuum box.
  • the known valve device is described in various embodiments: as so-called half-flap, in which the valve shaft is arranged eccentrically to the flap, or as a pivoting flap with central damper shaft arrangement.
  • a so-called angle flap with a centrally arranged pivot axis or flap shaft is also provided.
  • the Damper shaft is led out of the housing and connected via a suitable transmission mechanism with the vacuum unit, wherein the translational movement of the vacuum unit in a Rotations°. Swivel movement of the flap shaft is converted.
  • the exhaust flap is reset via the vacuum box, which in turn has a return spring.
  • the shaft of the valve closing member in particular the flap shaft of the exhaust valve is loaded by a torsion spring.
  • the term torsion spring is to be understood as meaning a spring element which is suitable for introducing a torque into the valve or flap shaft so that the flap is moved into an end position and held there.
  • Such a torsion spring element may thus have various structural embodiments, for. B. as a particular helical torsion spring may be formed. It is advantageous that the valve closing member or the exhaust valve is brought into a defined preferred position, even in the event that the servo motor is not mounted or fails during operation. In both cases, a rattling or fluttering and premature wear is avoided.
  • Torsion springs are also reached maximum possible holding forces for the exhaust flap, which is particularly important as a result of the high-frequency excitations of the flap by the pulsating exhaust gas flow.
  • This stable fail-safe position also has the advantage that the vibration friction wear of the valve shaft in the waveguide is considerably reduced.
  • Another advantage of the fail-safe position is that the transmission mechanism between the valve shaft and servo motor or vacuum unit is relieved, resulting in a reduction of material fatigue for these parts.
  • the return spring in the servo motor, in particular in a vacuum can be omitted, since the bias of the flap is already applied by the torsion spring according to the invention. In addition, the assembly tolerances improve considerably.

  • leg springs which are guided on a dome, are known per se as a machine element. It is advantageous that there is a favorable spring stiffness, in particular a large spring travel, which can be influenced inter alia by the number of windings.
  • the torsion spring can be arranged coaxially with the valve or flap shaft, wherein a guide sleeve is advantageously arranged on the valve shaft.
  • An advantage of the leg spring is further that the legs can be supported in a relatively simple manner on the one hand on the housing and on the other hand on the valve shaft.
  • the servomotor is designed as a pneumatically operated servomotor, that is, as a so-called vacuum box, which uses the vacuum of the intake system of the internal combustion engine as the working medium. Due to the torsion spring according to the invention and its arrangement on the valve shaft, there is the advantage that the return spring can be omitted in the vacuum unit. The vacuum box thus works against the action of the torsion spring according to the invention and adjusts the valve closure member or the flap in a different end position.
  • this will usually be the position in which the exhaust gas flow flows through the bypass channel, ie during the warm-up phase of the engine.
  • the vacuum supply is switched off, whereby the flap is transferred due to the torque of the torsion spring in its operating position, ie in the position in which the exhaust gas flow through the exhaust gas cooler and thus cooled by the coolant.
